Abstract
We have identified and characterized two antisense transcripts from the rat cytomegalovirus (RCMV) major immediate early (MIE) region. These transcripts, designated IE-AS1 and IE-AS2, are complementary to part of the sense IE1 transcript. The IE-AS transcripts were first detected in peripheral blood leukocytes (PBL) of RCMV-infected rats at 7 days post-infection (pi) in the absence of IE1 transcription. Nevertheless, both the IE1 and IE-AS transcripts were found at the same time in the salivary glands of RCMV-infected rats at 7 and 120 days pi as well as in RCMV-infected rat embryo fibroblasts (REFs) at 48 h pi.
